I did a small experiment PPT, the third part of the content: Comments on the sample essay

I did a little experiment

When I got home from school on Tuesday, I finished the homework assigned by the teacher. I picked up an "Encyclopedia" on the table, flipped through a few pages, and saw an introduction to an experiment: fill a cup with water and cover it with a piece of paper. Hold the mouth of the cup, and then turn the cup upside down with your hands so that the water will not flow out. I think this is absolutely impossible. How can a thin piece of paper hold up a heavy glass of water? ①

① Simply show that "I" saw the experimental introduction of "paper can hold water" and raised questions, which led to the experiment below.

"I have to verify it!" With suspicion, I started the experiment. ②First, I brought a glass cup and a piece of paper. I filled the cup with water, then covered it with the paper, and then turned the cup upside down. Hi! Really, the paper really holds up the water, a thin piece of paper really holds up the heavy water! ③But why can a small piece of paper hold up a glass of water? I read the "Encyclopedia" article introducing this little experiment several times, trying to find out its secret, but I just couldn't.

② Connect the previous and the following and point out the reasons for doing the experiment.

③ "First...then...then..." simply but methodically describes the process of the experiment and obtains the results.

I thought hard for a while and finally came up with a good idea - ask my knowledgeable dad. At this time, my dad was reading the newspaper in the living room. I walked over and asked, "Dad, do you know why a piece of paper can hold up a glass of water?" Dad said, "This is a good question, but you don't learn this until you go to junior high school." Yeah, I’m telling you, you don’t understand either, so why don’t you check it out online!”

Comments: The author uses concise and clear words, and clearly describes the reasons, process and results of doing this experiment. At the same time, it is interspersed with the author's own thoughts and questions, and he writes in detail about his exploration of the answer to the question "Why can paper hold water" (doing experiments, asking his father, and looking up information), and finally points out the truth he gained from it. It has a beginning and an end, and the emotions are in place.
